Archer C6 v3.2 gets disconnected from Internet. The internet light becomes red and then reconnects after a few seconds. This started happening after the last update which I installed sometime around 4 months back. It disconnects (at least what I noticed) 5-6 times per day and then reconnects automatically within a few seconds. 

Router is rebooted every day. It stays turned off for at least 5-6 hours per day.

I keep checking for firmware update every now and then from the router login console and update what gets automated form there

Internet provider is same and no changes done by them recently as well. Same provider, same package.

Can you help please?
